The7x4.5 inch 7045/7045R Propeller Pair (CW+CCW) is a set of counter rotating RC aircraft propellers perfect for use in twin and multiple motor RC airplanes or coaxial RC helicopters. You receive 2 propellers: One prop rotates Clockwise CW and the other prop rotates Counter Clockwise CCW (1 left hand & 1 right hand rotation). The length is 7 inches and the pitch is 4.5 inches per revolution.

This 7045 propeller can be used with brushless motors with a 800-2200 kV rating. With a low kV motor(800 – 1400 kV), this propeller offers smooth flights with longer flight times perfect for FPV and aerial photography. With a high kV motor (more than 1200 kV) this propeller offers fast flights perfect for acrobatic flights.
